The worst problem with these small connectors are the tools for crimping them. They are quite expensive, but it is very difficult to make a good crimp without them. If you can find someone who has one, then you are good to go. Otherwise, it is probably cost prohibitive unless you are doing a lot of work with those connectors.
I use the pico-blade connectors for most of my small connections, which are the same as the ones on the emag (1.25" pitch). I don't use them for solenoid connections.
You need to be careful when using a small connector on a solenoid. The current passing through it to activate the solenoid can exceed the rating of the connector. These small connectors are only rated to 1A. Check your current draw. Too high of a current draw will compromise the longevity of the connection due to heating at the point of contact.
Except for the Automag in front, its usually the man behind the equipment that counts.
